yea i know but i've seen these guy reach about 18 inches, i know i could get like 3-5 years before he would reach that size depending on what i feed him which is mainly spirulina flake with a mixture of hikari gold and omega one flake and he looks amazing, i did have a hole in the head problem a couple of months ago but it's completely cleared up after constant water changes and a reduction of carbon, but thank you i just wanna see what other say.
